AB The U.S. Army Corps of Engineers Lake-Erie Wastewater Management Study (LEWMS) produced a Land Resource Information System (LRIS) for water resources planning in the Lake Erie Basin. LRIS is a variable cell-size (4-36 hectares), computer-based, geo-referenced information system. It includes data on land use, soil characteristics, and political and hydrologic boundaries. These data were produced by LEWMS or generated by other planning agencies in the basin. Land use was determined by interpretation of high-altitude aerial photographs. Soil data came from soil surveys. Political and hydrologic boundaries were delineated on 7 1/2-inch topographic maps and coded for the data base.
